Response of fetal rat calvarial cells to nanotubular titanium oxide surface.

This study examined the cell response to a TiO2 nanotubular surface (Ti-NT) for future biomedical applications. The level of cell attachment and spreading at 20 min and 60 min was evaluated by SEM. IL-6 and PGE2 secretion was evaluated by ELISA.

The effect of nanotubular titanium surfaces on osteoblast differentiation.

The biological response of fetal rat calvarial cells on a TiO2 nanotubular surface (Ti-NT) was evaluated by cell viability assay, alkaline phosphatase (ALP) activity and reverse transcription polymerase chain reaction (RT-PCR) analysis. The cell viability assay showed no significant difference between the Ti-NT and smooth titanium surfaces (Ti-S). Ti-NT had better cellular responses with regard to the ALP activity and bone-associated markers, such as bone sialoprotein and osteocalcin mRNA than Ti-S.

Honokiol reverses alcoholic fatty liver by inhibiting the maturation of sterol regulatory element binding protein-1c and the expression of its downstream lipogenesis genes.

Ethanol induces hepatic steatosis via a complex mechanism that is not well understood. Among the variety of molecules that have been proposed to participate in this mechanism, the sterol regulatory element (SRE)-binding proteins (SREBPs) have been identified as attractive targets for therapeutic intervention. In the present study, we evaluated the effects of honokiol on alcoholic steatosis and investigated its possible effect on the inhibition of SREBP-1c maturation.
